O-SOX™The Easiest Downwell Deployment of Dissolved Oxygen
Affordable and effective oxygen-releasing socks for stimulating
aerobic biodegradation in ground water wells.
Applications: Stimulation of aerobic biodegradation of groundwater con-taminants using EHC-O™. EHC-O is deployed in ground water wells with the O-SOX™ delivery system. EHC-O is a proprietary field-proven compound that con-tains a long-term source of dissolved oxygen and nutrients. In the well, EHC-O reacts with water to release oxygen slowly. Exhausted socks are easily replaced with new ones to continue treatment. Organic constituents amendable to aerobic biodegradation processes are:• Petroleum Hydrocarbons• Light polycyclic aromatic hydrocarbons (PAHs)• BTEX
Benefits of EHC-O™❖ Significant cost savings realized through the use
of EHC-O due to its higher oxygen release rate and lower price.
❖ Contains nutrients. pH-buffered to reduce self-en-capsulation.
❖ Estimated longevity of 3 to 6 months.

Benefits of O-Sox™ Delivery System❖ All the field proven benefits of EHC-O.
❖ Substantial time savings in the field.
❖ Reusable stainless steel canisters are easy to insert in and retrieve from the well. Re-cover the cost of the canister in your first installation!
❖ Ease of determining the exact depth at which the product is deployed.
❖ Socks and canisters available for 2” and 4” wells.
❖ Up to three canisters may be suspended in line to lengthen the active zone.
❖ Even distribution of the active material over the length of the canister(s) because the socks do not collapse or bunch up.

Comparative Rates of Oxygen Delivery and Costs
EHC-O™ O-Sox™ FAQs
1. What are the main differences between O-Sox and comparable market alternatives? EHC-O O-SOX contains a well-buffered source of controlled release oxygen plus inorganic nutrients (mainly nitrogen) that can accelerate the biodegradation of various organic compounds and enhance certain natural attenuation processes. In addition, the O-SOX technology is a superbly well designed stainless steel canister and sleeve system which greatly simplifies installation, removal and replacement.
2. Do I need microbial inoculants? In most cases, the naturally oc-curring (indigenous) microorganisms are well adapted to the organic constituents of interest and inoculants are not required.
3. What contaminants are amenable to O-Sox treatment? The rate and extent of removal of all organic compounds that are biodegraded under aerobic conditions are usually enhanced via the addition of oxygen and inorganic nutrients. Petroleum-based aromatic (e.g., benzene, toluene, xylene, phenol) and aliphatic hydrocarbon mixtures (e.g., gasoline, heating oil, Diesel fuel, jet fuel, kerosene) are primarily targets; lightly chlorinated ethenes (vinyl chloride), MTBE, dioxane, pentachlorophenol, and many other compounds are also potentially amenable to O-Sox treatment.
4. How much do they cost? O-SOX cost about 25% less than market alternatives.
5. Why should I use the O-Sox technology? It’s a better product. And the superior design and ease of application will immediately translate into greatly reduced field time and frustration = reduced project cost.
6. Is it easy to switch over to the O-Sox technology? Yes. EHC-O has been accepted by many state regulatory authorities and it has been employed throughout the USA and Europe.
7. How long do they last? O-SOX are typically replaced every 3 to 6 months. Various site-specific factors will influence the effective life-time of the O-SOX cartridge; mainly i) constituent type and concentra-tion, and ii) hydrogeological features (groundwater flow rate, Eh, pH, temperature).
8. Do I need to install new wells? No. The O-SOX technology is designed to fit into standard 2-inch and 4-inch diameter groundwater monitoring wells. The canisters have a nominal outside diameter of 1.75 inches for the 2-inch size and 3.5-inches for the 4-inch size.
9. What is the oxygen delivery rate? The rated delivery is at least 15 lb of oxygen per 100 lb of EHC-O, after 200 days.
